^aEach mean represents 10 replications with 2 broilers per replication. CON, control diet; AFB₁, 500 μg/kg aflatoxin B₁ of feed; TA, 250 mg/kg tannic acid of feed; TA + AFB₁, 250 mg/kg TA + 500 μg/kg AFB₁.

^b T-SOD, total superoxide dismutase; GSH-Px, glutathione peroxidase; GST, glutathione S-transferase; T-AOC, total antioxidant capacity; MDA, malondialdehyde.

^a,b,cMeans in the same row with no common superscripts differ significantly (P < 0.05).
